PRINTING ATTACHMENT FOR SCALES Application filed November 20, 1925.

My invention relates to improvements in printing attachments for scales.

*lPhe object of my invention 1s to provide e printing attachment for scales m whichthe weight of the article being weighed 1s printed on e giunined strip of paper and ope "ated through it key mechanism, whereby the strip of guuirncd paper is fed forward so that it ce-n be torn cit end placed upon the wrapper oi the article being weighedso that the purchaser can see the exact weight of the no c Another object my invention is to pro vide printing attachment of this character which can be readily applied to the type oi scales in which rotary drum is used, carrythe weight scale on its outer periphery and the some exposed through an opening cssii'lg enclosing the drum urther object of my invention is to pro no for positively locking the printuin against movement during the ration so that the removal. of le 11611! the scale or the placing of thereon will in no way change the druin so that the exact weight of role will be printed on the gumrncd turther object st to provide a simple, cheep effective attachment or this character which is readily epplied to any of the well known scales and at the same time providing an attachment he very accurate printing of the exact my invention is weight of the article on the scales 1 1n the accompanying drawings Figure 1 is e side elevation of a scale showing my attachment applied thereto.

Figure 2 is c, front view of Figure 1.

Figure 3 is o transverse horizontal sectional. view taken on the line 3-3 of Fig ure 1.,

Referring now to the drewings t repre sents the base ct n standard scale which has the weighing platform 2 mounted on the pin 3 which operates as mechenisrn within the base 1 which extends up through the housing t, and this mechanism operetes the bar 5, which cerries a rack engogin the pinion 6 carried by the scale drum this scale drum is enclosedwithin the housing 8 and said housing has an opening 9 therein,

which has it cross wire 10 by means or which the scale 11 on the outer periphery of the drum 7, may be readily read. All of the above described structure is old and the same 34 to the base 1 of the scale.

existing the printing mechanism as Serial No. 70,344.

is simply shown and described to show the application of my invention. The shaft 12 of the scale drum 7 extends out through the end 13 of the housing 8, and has mounted thereon my improved printing drum 14. This drum 14 has on its outer periphery type to correspond with the reading of the scale marks on the drum 7 so that when five pounds register with the wire 10, the type indicating five pounds will be at the point 15 on the drum 14:.

The .outer face of the drum 14 has a disc 16 secured thereto, and having teeth 17 on its outer periphery. Arranged below the disc 1e and carried by the housing 4, by means of the screws 18, is a guide way 19, through which the gummed strip 20 passes, and the outer edge of which serves as means for severing the printed portion of the strip from the roller. Carried by the housing 8 are the two drums 21 and 22, around which is wound. the inked ribbon 23 which rests upon the upper face of the guide way 19. A shaft 2% is mounted on a bracket 25, carried by the housing 4, and upon which is wound the gummed strip 20, which passes upwardly over the feed roller 26, mounted on the shatt 27. Carried by the bracket 23 is a leaf spring 27 which holds the gumrned strip down upon the roller 26 and whereby the strip is fed forward upon the rotation of the roller. The shaft 27 is provided with ratchet wheel 28, which is engaged b ratchet teeth 29 carried by the bar 30. A. guide 31 is provided through which the bar passes and whereby it can freely reciprocate and have a lateral movement so that the teeth of the bar can disengage the ratchet wheel 28. The lower end of the bar 30 is pivotally connected at 32 to the operating lever 33 which is intermedintely pivoted at The outer end of the lever 33 extends beyond the base of the scale so that it may be depressed for o will be readily described.

The lever 33 is provided with a spring 35 which engages the bar 30 so that the ratchet teeth carried thereby will normally hold in enga emcnt the ratchet wheel 28, carried by OIL K strip.

travels upwardly through an opening 40 in the guide 19, and carrying with it the gummed strip 20 and the inked ribbon 23, so that the strip 20 will receive the impression from the type on the drum 14, at the point 15, and thus print the weight ofthe article on the platform 2 of the scale on the strip of gummed paper. The printing bar 37 at one side of the printed face 39 is provided with a detent 41 adapted to engage the teeth 17 and hold the type drum so that it can not be moved during the printing operation.- This detent 41 engages the teeth 17 prior to the actual engagement of the printing face 39 with the type of printing drum.

In operation, the article to be weighed is placed upon the scale platform 2, and through the mechanism 2 and 5 the drum 7 is oscillated to indicate the proper weight and simultaneously therewith the printing drum 14 is moved to bring the type corresponding withthe weight indicated on the drum to the point 15. The lever 33 is then depressed, rocking it upon the pivot 34, moving the printing bar 37 upwardly and causing the printing face 39, carried thereby, to move the gummed strip upwardly against the inked ribbon 23, and the continued move- I ment of the printing bar causes the detent 41 to engage the teeth 17 of the printing drum and locking the same against movement. This causes an impression of the type at the point 15 to be made on the gummed The downward movement of the outer end of the lever 33 causes the bar'30 to move upwardly, and the ratchet teeth will slip over the teeth of theratchet wheel 28, and the gummed strip will remain in a stationary position ,lVhen pressure is relieved on the outer end of the lever 33 the spring 42 will draw the inner end downwardly, and the spring 35 holding the bar 30 against the ratchet wheel 38 the feed roller 26 will be rotated, causing the gummed strip to be fed forward through the guide way 19. The gummed strip can be pulled by hand so that the printing portion will be beyond the guide way and can then be torn off and pasted on the wrapper of the article previously weighed.

Having thus fully described my invention what I claim is The combination with rmting drum thereon, and operated therey, a paper feeding mechanism for feeding the paper below the drum, a printing face adapted to force the paper against the drum, and a ri id detent carried by the printing face for ocking the drum against movement Justprevious to the printing operation.
